Özet

This study aims to investigate antimicrobial effects of chitosan obtained from shell wastes of Metapenaeus stebbingi on refrigerated rainbow trout fillets. In the study, the fillets were dipped with different concentrations (0.1%, 0.5%, 1%) of extracted and commercial chitosan and were packed with vacuum and air conditions and subsequently, changes in total bacteria were observed during refrigerated storage period (4 +/- 1 degrees C). There were decreases in the number of microorganisms of both groups plunged in natural and commercial chitosan during 12 days of storage compared to control group, and the best results was obtained as 0.1% in the groups applied with natural and commercial chitosan (p<0.05). In conclusion, chitosan obtained from shell wastes of M stebbingi could be used as an effective natural alternative to synthetic antimicrobial agents during the storage period of fish.
